Conditions that require immediate filter replacement.
1. Cleaning ceramic filter no longer restores flow rate.
2. Following a “Boil Alert” from local water supplier.
3. Running HOT water through the unit
4. If there is a breach in the ceramic or any noticeable
cracks in the ceramic.
The following are guidelines on when to change your filters.
All filters have a variable life-span which is dependent upon:
1. Levels of chemicals and heavy metals in source water.
2. Number of people using the filtered water
3. Amount of sediment and dirt in the water.
4. Sudden high dosing of the water with chlorine or chloramine
5. Size and number of filters in your unit.
1-2 people: 9-12 months
3-4 people: 6-9 months
4+ people 6 months or less
GUIDELINES FOR FILTER REPLACEMENT
FACT: Even if water is flowing through the ceramic filter after clean-
ing, the filter will NOT last beyond one (1) year. The reason is that
the carbon block inside the ceramic is adsorbing the chemicals
and heavy metals and becomes saturated. If you do not change the
filter at the recommended time, the trapped chemicals will leach off
the filter and increase the contaminant level of your drinking water.
FACT: Most contaminants such as parasites, bacteria, and lead do
not cause an off taste. On the other hand, if the filtered water does
have an off taste that usually indicates that the carbon block is satu-
rated and needs to be changed.
We want all of our customers to be fully protected from toxic
substances in your water. Please change your filters on schedule.
Due to filtration of particulate contaminants (dirt) from the water dur-
ing use, the flow of water from the filter may reduce over a period of
time. To restore the water flow to its normal level simply remove,
clean and replace the filter cartridge as follows:
____________________________________________________________
1) Open the white housing sump on the filtration unit by placing a
bucket under the unit. Unscrew the white housing sump clockwise
using housing wrench. The sump will be full of water. Discard the
water and remove ceramic filter.
2) Use a non-detergent, abrasive pad, (Scotch Brite) and lightly
brush the ceramic filter under cold water until clean. NEVER USE
SOAP OR ANY CLEANING AGENTS. Do not rub the filter too hard
as it will cause excessive wearing of the ceramic and may cause it
to crack.
3) Clean the inside of the base and sump with a 50/50 solution of
water and peroxide using a vegetable scrub brush. DO NOT USE
THIS BRUSH FOR ANY FOOD PROCESSING. Clean threads of
housing with a cotton swab ( Q-Tip).
4) Reinstall ceramic filter into the sump and screw in the housing
sump counter clockwise into the base. MAKE SURE “O” RING IS
SEATED PROPERLYor the filter will leak. (Vaseline can be used to
secure O-Ring in housing sump)
5) NOTE: The other filter can not be cleaned!
6) If flow rate is not restored, contact CWR for further instructions.
Even if the water is flowing through the filter after cleaning,
the filter will not last beyond one year.
